For installations that pass through a vertical wall and not through the roof, Country Flame
recommends an installation similar to the one shown in FIGURE 3. Dimension A should be a
minimum of 16” and dimension B should be a minimum of 3”. Any outside vent should have a
vertical run of at least 5’. At the same time, ensure that termination of the flue pipe does not
occur just under the roof overhang. Such a termination can cause smoke to seep back through
the roof and into the home. For all flue pipe runs over 5’, there should be a flue support no less
than 5’ apart.

FIGURE 3: RECOMMENDED EXTERIOR WALL INSTALLATION
All installations may include a fresh air combustion pipe at least 1 ½” diameter. Such a pipe can be
plastic, rigid metal, or flexible metal pipe. In newer homes, it is strongly recommended that an
exterior fresh air combustion vent be installed to ensure proper amounts of air are provided to the
pellet stoves combustion chamber.
